Oscillation frequency fosc. in this circuit is expressed
approximately by the following equation.

This clearly shows that the oscillation frequency is
influenced by the loading capacitance. And caution
should be paid in defining its value when a tight
tolerance of oscillation frequency is required.
Application to C-MOS Inverter
For the C-MOS inverting amplifier, the one-stage 4069
C-MOS group is best suited.
The C-MOS 4049 type is not used, because the three-
stage buffer type has excessive gain, which causes RC
oscillation and ringing.
Murata employs the RCA (HARRIS) CD4069UBE as a
C-MOS standard circuit. This circuit is shown in
Fig. 4-2. The oscillation frequency of the standard
CERALOCK
circuit in Fig. 4-2.
